I actually knocked King Yan and my CP!

Zhu Gaoxu watched the personal servant walk back and forth in front of him, and said impatiently: "What the hell are you in a hurry for?"

The personal servant said aggrievedly: "Your injury is so serious, how can you drag it on?"

Zhu Gaoxu curled his lips, "When am I going to procrastinate, didn't this military doctor show me?" Although he was irritable, he was kind to the old man who had been with him for many years.Therefore, although the servant's words were not in line with his wishes, Zhu Gaoxu did not get angry.

He bent his feet and leaned back. The pain in his thigh made Zhu Gaoxu's scalp numb. It's unlucky that he still hurt his leg.

If it hurts other parts, it is not difficult as long as you can still mount the horse, but if you hurt your leg, there is nothing you can do, you can only take good care of it.Fortunately, although Zhu Gaoxu's injuries looked serious, they were all flesh injuries, and it would be better if he took more time to heal.

"That He Yuxuan really won't come!" The servant cursed in a low voice, and then went to arrange meals for Zhu Gaoxu.Although Zhu Gaoxu was a little irritable, but looking at him, he didn't look angry at all.

Zhu Gaoxu didn't plan that He Yuxuan would really come over.

According to He Yuxuan's habits, he is a cautious and introverted person. Before he is sure what Zhu Gaoxu means, he will definitely not come to the front line.

Otherwise, if He Yuxuan died on the battlefield with a "flowing arrow" mistake, how would he know?

This time Zhu Gaoxu honestly hoped that He Yuxuan would come to see him.It's good to be able to come, if not... Zhu Gaoxu showed an unusually gentle smile.

After all, Zhu Gaoxu's status is much nobler than that of He Yuxuan, but He Yuxuan can't resist... This matter is not big, but it is not small.

Now that He Yuxuan is still needed, Zhu Di will naturally not say anything because of this. If He Yuxuan is useless in the future, today's move will be He Yuxuan's fatal Achilles' heel!

Even Zhu Gaoxu's identity can't command him, does it mean that he has two minds?

Regardless of whether he has two minds or not, Zhu Gaoxu will be able to break in this direction at that time, and then we will see who can speak for whom...

Zhu Gaoxu is very confident in his nonsense skills.

"Ahem..." He coughed a few times. After all, he was still a little sick. After the cough passed, he waved to the guard at the door, "Go and watch outside, so I can rest for a while."

With Zhu Gaoxu's current injuries, he doesn't need to go to the battlefield.

"Yes!"

The guards went out to guard, and the big tent immediately became quiet.

Zhu Gaoxu fell asleep contentedly, and the world in his dream was extremely moist.

……

Somewhere in Beiping, there is a valley in a hill.

Jin Zhong squinted his eyes at the newly released firecracker, and asked the blacksmith, "What's the range?"

"The shooting range is one-half higher than the original." The blacksmith said happily: "And the whole wooden barrel is very tough, and the possibility of jamming and collapse is much lower."

Jin Zhong held up the fire blunderbuss, and casually fired at the tree trunk outside the window.

whoosh-

He signaled the guards around him to take a look with his eyes.

Not long after, the guard came back and said in a low voice, "The penetrating power is very strong, and you can't get it out if you penetrate three points."

Jin Zhong nodded in satisfaction, "Is this kind of firecracker capable of energy production?"

The blacksmith looked a bit embarrassed, "We can work hard to produce, but it's still a little too late to reach the level of an army."

Jin Zhong sighed, "How about the stability? If I transfer two-thirds of the front manpower to you to take charge of this part, can you only do [-] in half a month?"

The blacksmith gritted his teeth: "Of course it is possible!"

The most important thing in this matter is technology and materials, the stability of the wooden warehouse pipe, and other things are easy to talk about.All the parts can be disassembled, and the most important parts can be divided by skilled veterans. Twenty pieces a day is still possible.

Jin Zhong has agreed to transfer the most scarce manpower, how can it not be possible? !

Jin Zhong nodded, and in that case, he suspended the homework at hand, and went all out to finish this new type of firecracker first.

He believes... the prince will be very satisfied.

At the same time, He Yuxuan was coughing and crawling out of the pile of debris, his eyes were a little uncomfortable from the dust.

This is Liu Sheng's warehouse. When He Yuxuan followed him to look at the fields, he saw that Liu Sheng couldn't find what he wanted after searching for a long time, so he also went in to help... Of course, there is also a reason why the house is cooler.

Unexpectedly, this warehouse has a history of unknown years. The two people were shocked by the messy furnishings when they entered, "Your warehouse can be made like this, it's just a pile of debris."

Liu Sheng said embarrassingly, "This was originally my hometown, but after I moved to the city, few people came here."

Liu Sheng went into the warehouse and rummaged for a long time, finally found what he wanted, and happily showed it to He Yuxuan, "Is this what you said?"

He Yuxuan recognized it for a long time, then nodded, "This is indeed a lens."

Liu Sheng's father was originally a peddler in the streets and alleys. He has a wide network of contacts and can get all kinds of weird things. This crystal lens, which is similar to glass, was also obtained by Liu's father before.

"But what's the use of this?" Liu Sheng was very curious.

He Yuxuan smiled and said, "You will know later."

What he's trying to do is a telescope.

This telescope can play a great role in the military, so there is no need to introduce it, but He Yuxuan suddenly thought of getting this, in fact, it was because of the suggestion made by the fellow in the small black room last night.

Although he didn't know if it could be done, He Yuxuan still wanted to try it.

Just practice with a telescope first.

In the fanfare last night, He Yuxuan was a scout, ah, according to the book, he was an observer, and his partner Zhu Di was a sniper... He Yuxuan neutralized the general meaning, he should be an archer.

Although no matter how you look at it, it is a waste to pair an archer with an observer.

Observers need to be responsible for observing the surrounding environment and inform the snipers of relevant information from time to time. He Yuxuan learned a simple tutorial on making a telescope.

I hope it is really simple... He Yuxuan recalled the long speech, and wanted to vomit blood.

"Isn't it better...?" Liu Sheng suggested hesitantly.

He Yuxuan: "...OK, let's try it?"

"No, it's crooked here, what if it's changed to this..." He Yuxuan muttered to himself, dismantled the original build, and continued to change his mind. This telescope tutorial only tells He Yuxuan how to do it It is the most suitable, but the difficulties encountered in this process are directly mentioned, causing He Yuxuan to often get stuck.

In the end, He Yuxuan discovered that the crystal lens is convex, and at least one opposite concave lens is needed.

He pondered for a moment, then took Liu Sheng into the city, ran all over the city, bought a single-view lens from the only store in the whole city that had a single-view mirror, and opened the single-view lens, and stuffed the lens into a In a cylinder made of cardboard.

He Yuxuan worked hard for half the morning, and finally came up with a four-dimensional image.

These four differences mean that the telescope still cannot be adjusted in size, and the magnification factor is already constant. As long as you put the telescope in front of your eyes, you can directly see the size of people in the distance, and you can even see them clearly. to action.

He Yuxuan pondered for a moment, and then asked: "Is there any shop in Beiping that sells imported products?" He changed his mind, not necessarily a single photo, maybe some imported products also have lenses.

Liu Sheng smiled bitterly and shook his head, "Never. Although there are occasional imports from foreign countries, they are basically enjoyed only in Jiangsu and Zhejiang areas. It is really rare to circulate in the north. It costs too much. Big, and few people are willing to take that risk."

After all, the Ming Dynasty has not yet opened up shipping, and not many folks have taken this road.Shipping by sea is not a simple matter, especially prone to accidents.Once an accident occurs, the entire army will be wiped out, and all his wealth will be thrown into the sea. No matter how adventurous a normal businessman is, before a safe route is opened up, it will take time for this imported product.

He Yuxuan rubbed his chin. He bought all the single photos in this store, but there were only a dozen at most. If they were really used to try to make, this number is still a bit small.

That's all, let's talk about one thing, and talk about two things. While there is still this amount, let's grind out the telescope first.

If it’s not possible, just look for a craftsman who knows this craft to grind out the necessary lenses.

He Yuxuan took these small objects and bid farewell to Liu Sheng. After returning home, he studied hard and stayed behind closed doors all day, scaring Brother Ying for most of the time. He was afraid that Master He would just pass by in the house this summer.

He Yuxuan: This must be how distrusting him.

This summer is scorching, approaching the end of April, and it is hot inside and outside the house.He Yuxuan also had a share of ice cubes in this room, but He Yuxuan threw them into the ice storage.Firstly, it is easy to catch cold, and secondly, it is a waste. He Yuxuan is not that afraid of heat, but occasionally let Brother Ying and the others take some to use.

Two days later, He Yuxuan finally crawled out of the room, and lay down on the table, refusing to move.

Ma Han poked him disrespectfully, "Master He, what's wrong with you?"

He Yuxuan said weakly: "Where is Liu Guan?"

"Here!" Ma Han pulled out Liu Guan from behind the door, and dragged him to He Yuxuan.

He Yuxuan handed him a strange cylindrical object in his hand, "Go up to the wall now, and hold this object in front of your eyes to see how it goes."

Without saying a word, Liu Guan directly took the cylindrical object and went there.

Ma Han had a look of disbelief, and said sadly: "My lord, I am right in front of your eyes, why don't you look at me?"

He Yuxuan looked at him lazily, "Do you really want to know what this is for now, and you have a lot of questions in your stomach?"

Ma Han nodded obediently.

He Yuxuan got down completely, and his voice came out muffled from his arms, "That's why I didn't let you come."

Ma Han cried, "I don't have that much to say..."

Brother Ying stared at him silently, this remark was worse than Master He not being lazy!

Amidst the uproar between Ma Han and Brother Ying, Liu Guan drifted in, eyes full of bewilderment and shock, holding the cylindrical object and muttering to himself, "I actually saw Chief Liu..."

It doesn't matter if you see people, but you can see the patterns on people's clothes clearly, which is really surprising!

Ma Han narrowed his eyes, suddenly felt that it was not easy, grabbed the cylinder in Liu Guan's hand, and rushed out.

Liu Guan let Ma Han move, but after shouting "Don't break it", he looked at He Yuxuan in shock, "My lord, how did you do this? Could it be..." His voice gradually faded. Low, said hesitatingly: "Monster?"

He Yuxuan:? ? ?

Liu Guan, what's the matter with you thick eyebrows and big eyes?

Why did you still think of the monster?
